Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 1; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 10 - 11; ऐनल सौफट रेज़: 12 - 13. Diagnosis: body rather elongate, 6 times longer than deep; occipital process 3-5 times longer than broad (Ref. 57125). 10-11 branched dorsal-fin rays (Ref. 57125), 1st extended into long filament, following into shorter ones (Ref. 7324, 31256, 57125). Longest filament comprised 2 to 3 times in standard length (Ref. 3036, 57125). Predorsal length comprised 2.6 to 2.9 times in standard length; head width 1.6-1.9 times in head length; width of premaxillary tooth plate 2.4-2.8 times in head length; upper caudal-fin lobe often prolonged into a short filament (Ref. 7324, 57125). Upper caudal-fin lobe comprised 2.5 to 3.5 times in standard length (Ref. 57125).

Eats fish (Ref. 51193).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00832 (0.00384 - 0.01800), b=2.95 (2.77 - 3.13), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.9 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): ऊंचा, न्यूनतम जनसंख्या दुगनी समय अवलागत 15 महीने। (Assuming Fec>10,000).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100).
